[PATCH] D88385: [TableGen][M68K] (Patch 1/8) Utilities for complex instruction addressing modes: CodeBeads and logical operand helper functions

[Paul C. Anagnostopoulos via Phabricator via llvm-commits]

Paul-C-Anagnostopoulos added a comment.

If it isn't possible to encode the information in TSFlags, another possibility is to add a pointer to the MCInstrDesc class that points to some kind of auxiliary class/struct. It would be unfortunate to increase the size of MCInstrDesc, though. I have been playing with the idea of changing the three pointer members to indexes in order to save memory, but I'm not yet convinced it's worth the effort. There are about 67,000 instances across the targets.
